Definitions

  • the present invention relates generally to photographic diffuser lightbanks or soft boxes and more specifically to releasable rod or pole anchors for rods or poles that support lightbanks in extended, outstretched configuration.
  • Photographic diffuser lightbanks also sometimes known as light boxes or soft boxes, are commonly used by photographers and film makers to control the distribution of light on subjects. Devices of these types are disclosed, for example, in the following U.S. patents: Inventor Patent No. Larson 4,446,506 Regester 4,669,031 Regester 5,023,756 Kester 6,076,935
  • Lightbank assemblies typically include a diffuser panel for scattering light rays emanating from a bright light source, which may include a light bulb or filament, a hood or body formed from fabric or other soft material with a reflective interior surface for confining and directing the light rays from the light source to the diffuser panel, and a support structure for supporting the reflective hood and diffuser panel over the light source.
  • the mounting structure typically comprises a ring-shaped frame or other mounting component for attachment of the light bank assembly to the light source, and a plurality of support rods or poles that extend forwardly and outwardly from the ring-shaped frame to support the reflective hood and diffuser panel.
  • the support rods or poles are usually formed from resilient metal, graphite, plastic, or other materials that can be bowed against an inherent bias or resistance by application of external forces, but which spring back to their original shapes upon removal of such forces.
  • One common approach for mounting the support rods or poles to the ring-shaped frame includes cylindrical holes in the ring-shaped frame.
  • the proximal ends of the respective support rods are inserted into the holes in the ring-shaped frame so that they extend forwardly and outwardly from the ring-shaped frame at an angle that will cause them to be resiliently strained or deformed into a bowed or arced state when the reflective hood is mounted on the rods, while the fabric of the reflective hood body is stretched in tension.
  • This combination of bowing and tensile forces or stresses enables the rods to support and hold the reflector hood and diffuser panel of the lightbank in their operative position extending forward and outward from the ring-shaped frame.
  • EP 0 964 291 A1 relates to a collapsible light reflector comprising rods which are pivotably mounted on an assembly of rings circumferentially surrounding a corresponding light source. Each rod is fixed to a lever unit pivotably mounted in a radial transverse slot of the rings.
  • the lever unit consists of a socket into which the rod is inserted, a cylindrical portion connected to the bottom of the socket and a flat arm formed at the end of the cylindrical portion and extending into the radial transverse slot.
  • a sleeve being moveable along a longitudinal axis of the lever unit is provided on an outside thereof.
  • a reduced diameter portion of the sleeve slides about an outside surface of the fixed ring assembly when the lever unit is pivoted from a position according to which the light reflector is collapsed to an operative position according to which the rods are under tension. In the operative position, the reduced diameter portion, of the sleeve is positioned within the radial transverse slot.
  • US 4,606,366 relates to an umbrella comprising an arm to which a radial arm is pivotably mounted. When the umbrella is opened, the arm pivots upwardly. This upward movement is assisted by a traction spring provided within the tubular arm and connected to a point within the radial arm via a cable.
  • a hand lever is pivotably provided on the arm and comprises on a distal end a cavity, which corresponds to a ball of a projection of the radial arm. When the arms have reached their final position, the operator manually pivots the hand lever towards said ball and brings the cavity into locking engagement herewith.
  • US 2002/0075666 A1 , CH 645 735 A5 and US 4,594,645 relate to umbrella-like lightbank assemblies in which support rods are held in their operative position by means of struts. Each of the struts is always pivotally mounted to the respective support rod and a central member.
  • the support rods comprise an integral joint part at one of their ends by means of which they are pivotably fixed to a base part.
  • the object is solved, according to the present invention, with a releasable support rod mount having the features of independent claim 1, and with a mounting method having the features of independent claim 5.
  • an improved light bank assembly that can be conveniently set up and collapsed.
  • One embodiment of the invention may include a plurality of pivotal and latchable anchor blocks pivotally mounted on a ring-shaped frame for mounting the support rods or poles of a light bank assembly to a base of light source.
  • the latchable anchor blocks or mounts may be movable between an operative or latched position at which the support rods are anchored in the blocks and extended forwardly and outwardly to extend and support the lightbank reflective hood and diffuser panel in an outstretched conflguration, and a released position at which the support rods and reflective hood can be collapsed.
  • a lightbank assembly 8 including releasable gimbals or pivotal support rod mounts 10 in accordance with a first embodiment of the invention is illustrated generally in Figure 1 .
  • the lightbank assembly 8 is shown mounted to a light source 12, which may include an electric light bulb, filament, or other light producing element, supported by a stand 14.
  • the lightbank assembly 8 includes a ring-shaped frame 16, which is often called simply a ring, a plurality of support rods 18 and a light reflection hood 20 made of fabric or other soft, flexible, sheet material with a reflective interior surface supported by the rods 18.
  • a light diffuser panel 21 is mounted on the distal ends 19 of the support rods 18 over the open end of the reflector hood 20.
  • the diffuser panel 21 comprises a translucent sheet 23 of material that transmits, but scatters or diffuses light produced by the light source 12.
  • Ring 16 is configured for mounting the lightbank assembly 8 to the light source 12. While there are many sizes and configurations of ring-shaped frames that are suitable for this invention, the illustrated embodiment of ring 16 includes a mounting member 22 that is mounted directly to the light source 12 and a frame 24 that is mounted to and extends around the mounting member 22.
  • the support rod mounts 10 are attached to the frame 24 of ring 16 in this particular embodiment, such as by screws, welding, or the like. In other embodiments (not shown) the support rod mounts 10 can be attached directly to the mounting member 22 of the ring 16 or to any other sturdy part of the ring structure. Therefore, references herein to components mounted in pivotal relation to the ring or frame include direct pivotal mounting to the ring or frame or indirect pivotal mounting, such as, for example, pivotal mounting to another component that is, in turn, attached to the ring or frame.
  • Support rods 18 are connected to, or anchored in, the ring 16 by the releasable mounts 10.
  • the support rods 18, or at least portions of the rods are usually formed from resilient metal, polymers, graphite, or other materials that are bendable or deformable by external forces, but which spring back to their original shapes upon release of such forces. Rods of these types are well known and commercially available from a number of photographic equipment suppliers including Chimera Company of Boulder, Colorado.
  • the support rods 18 When the releasable mounts 10 are in the operative position shown in Figure 1 , the support rods 18 will be bowed or arced from their neutral state and apply sufficient tension to the reflector hood material 20 of the lightbank assembly 8 to fully extend and outstretch the light reflector hood 20 and diffuser 21.
  • the strained support rods 18 effectively function as a support frame for the reflector hood 20 and diffuser panel 21.
  • the mounts 10 When the mounts 10 are in their released position (not shown in Figure 1 ), the mounts 10, and therefore the support rods 18, move toward one another, thereby relieving the tension applied to the reflector hood 20 and allowing the support rods 18 and reflector hood 20 to be collapsed into a reduced volume.
  • FIG. 1 solid lines are used to illustrate the reflector hood 20 in its extended or outstretched state or a configuration for use, and broken lines illustrate the reflector hood 20 in its collapsed state 20'.
  • the lightbank assembly 8 can be relatively easily transported when collapsed.
  • a significant feature of this invention is the pivotal mounting blocks 10 for mounting and anchoring the support rods 18 to the ring 16.
  • These mounting blocks 10 are latched or pinned in a non-pivotal relation to the ring 16, when the support rods 18 and reflector hood 20 are outstretched in their use configuration, as described above.
  • the mounting blocks 10 can be unlatched or unpinned, as will be described in more detail below, to release the mounting blocks 10 to pivot about respective pivot axes to allow the support rods 18 and reflector hood 20 to collapse toward the longitudinal axis 25 of the lightbank assembly 8, as shown by the phantom lines 20' in Figure 1 .
  • latching and pinning accomplish the same result, as will become more clear as the description proceeds, so these terms may be used interchangeably at times and one should not be construed to exclude the other, but should be construed to include the other.
  • the pivot axes of the respective mounting blocks 10 preferably lie in a plane that is perpendicular to the longitudinal axis 25, although other orientations of the pivot axes would also work.
  • each support rod 18, when anchored in the pivotal support block 10, can be grasped and forcibly pulled or pushed outwardly, away from the longitudinal axis 25, to its outstretched, use position, as shown in Figure 1 , as the pivotal mounting block 10 pivots along and reaches a latch position where it can be latched or pinned to hold the support rod 18 and reflector hood 20 in their outstretched positions.
  • the pivotal mounts or mounting blocks 10 include a base 30 that comprises at least one, but preferably two spaced apart, journal boxes or members 32 for supporting or holding a pivot pin 38 that defines a pivot axis, a rod anchor block 34 (sometimes called a rod block, anchor block, or block) mounted on the pivot pin 38 to pivot or rotate about the pivot axis, and some kind of latch or pin to releasably fix or prevent the rod anchor block 34 from pivoting or rotating about the pivot axis.
  • a base 30 that comprises at least one, but preferably two spaced apart, journal boxes or members 32 for supporting or holding a pivot pin 38 that defines a pivot axis
  • a rod anchor block 34 (sometimes called a rod block, anchor block, or block) mounted on the pivot pin 38 to pivot or rotate about the pivot axis
  • some kind of latch or pin to releasably fix or prevent the rod anchor block 34 from pivoting or rotating about the pivot axis.
  • the latch comprises a release lever 36 mounted on a latch pivot pin 51 and which has a first latch surface 54 that interfaces with a second or mating latch surface 56 on the rod anchor block 34 to releasably prevent the rod anchor block 34 from pivoting or rotating about the pivot axis of pivot pin 38.
  • the base 30 can be attached to the ring 16 by screws 35 or other fasteners that extend through holes 37 in the frame 24 into members 32 or by welding (not shown) or any other attachment method.
  • the base 30 could also be an integral part of the ring 16, or it could be a separate component that could have a plate (not shown) or other component that extends under the anchor block 34 to support the two journal boxes 32 and that is attachable to the ring form 24.
  • Rod anchor block 34 is pivotally mounted to the base 30 by the pivot pin 38, which extends into the rod anchor block 34 and into holes 40 in members 32.
  • the pivot pin 38 can be rotatable in either the journal box members 32 or the rod anchor block 34, or both, to allow rod anchor block 34 to pivot or rotate, as indicated by arrow 39, between the operative position shown in Figures 2 and 3 (causing the rods 18 to be strained and the reflective hood 20 to be under tension) and the released position shown in Figure 4 (causing the rods 18 and reflective hood 20 to be collapsed).
  • the rod anchor block 34 includes a cylindrical hole 42 for receiving the proximal end 17 of a support rod 18.
  • Another optional hole 44 with a different diameter and/or extending at a different angle into the rod anchor, block 34 can be provided to accommodate a different sized rod 18 and/or a different sized reflection hood 20.
  • smaller reflector hoods 20 usually have smaller diameter support rods 18 (not shown) that extend at a larger angle outwardly from the longitudinal axis 25 than larger reflector hoods 20 with larger diameter support rods 18, and the optional hole 44 with the different diameter and different angular orientation than hole 42 accommodates such different sizes.
  • optional threaded bores 46 and 48 extending through the block 34 and into intersection with holes 42 and 44, respectively, and can be used with fasteners, such as set screw 50, to further secure the proximal end 17 of the support rod 18 in the anchor block 34.
  • Rod anchor block 34 is releasably clamped or latched in its operative position by latch lever 36.
  • the latch lever 36 is rotatably mounted to the base 30 by pivot pin 51, which extends into the lever 36 and through holes 52 in members 32.
  • the pivot pin 51 allows the lever 36 to rotationally move, as shown by arrow 64, between a clamped or latched position shown in Figure 2 and a released position shown in Figure 4 .
  • a lip surface 54 on the lever 36 engages a shoulder surface 56 on the rod anchor block 34 when the rod anchor block 34 is in the operative position and the lever 36 is in the clamped or latched position ( Figure 2 ).
  • a spring 58 such as a piano spring, cooperatively mounted between the lever 36 and base 30 biases the lever 36 toward the clamped or latched position.
  • the lever 36 also has a transition surface 60 adjacent the lip 54 that cooperates with cam edge 62 on the shoulder 56 of rod block 34 to cam the latch lever 36 against the bias of spring 58 as the anchor block 34 is pivoted toward the latched, operative position.
  • first latch surface 54 of lever 36 be substantially perpendicular to a radial line (not shown) that extends from the lever pivot axis 53 through the latch surface 54 so that the latch lever 36 can be moved without unnecessary resistance toward the unlatched position, when the anchor block 32 is under a lot of stress from the loaded rod 18, yet is also effective to secure the latch in the operative position of Figure 2 , when the rod 18 is loaded.
  • the mating latch surface 56 on anchor block 34 is also preferably in that same orientation, when the anchor block 34 is in its latched, use position, as shown in Figure 2 .
  • the latch surface 54 is essentially tangential to, or an arc of, a circle 55 that is concentric to the lever axis 53, and the second latch surface 56 aligns and mates with the first latch surface 54, when the lever 36 and anchor block 34 are in the latched position.
  • a technician When setting up lightbank assembly 8, a technician will insert the proximal ends 17 of support rods 18 into the holes, such as 42, of the rod anchor block 34. This maneuver can be performed when the rod anchor block 34 is in the operative position shown in Figure 2 or in the released position shown in Figure 4 . If a support rod 18 is inserted into the rod anchor block 34 when the rod anchor block 34 is in the released position, the technician will typically grasp the rod 18 and rotate the rod 18 and anchor block 34 toward the operative position.
  • the cam edge 62 on the rod anchor block 34 will engage the transition surface 60 on the lever 36 and urge or cam the lever 36 toward its release position against the bias force of spring 58 until the cam edge 62 passes the end of lever lip 54 and the anchor block 34 reaches its operative position.
  • the spring bias force on the lever 36 will cause the lever 36 to move to its clamped or latched position with the first latch surface 54 on lever 36 engaging the second latch surface 56 on anchor block 34 and thereby hold the rod anchor block 34 in the operative position against the force applied to the anchor block 34 by the strained rod 18.
  • the technician can easily collapse the reflective hood 20 by grasping and moving lever 36 toward the release position (away from the rod block 34 in the direction of arrow 64 in Figure 2 ), thereby disengaging the lever 36 from the rod anchor block 34.
  • Releasable mount 110 a second embodiment of the present invention, is illustrated in Figure 5 .
  • Releasable mount 110 is similar to mount 10 described above, and features with similar functions are indicated by similar reference numbers.
  • the mount 110 includes a base 130 having a pair of journal boxes or members 132 (only one is shown) integrally mounted to ring 116.
  • a rod anchor block 134 and a release lever 136 are pivotally mounted to the base 130 by pivot pins 138 and 151, respectively.
  • the lever 136 is biased toward its clamped or latched position by spring 158.
  • the lip surface 154 and transition surface 160 of release lever 136 cooperate with the shoulder surface 156 and cam edge 162 of the rod anchor block 134 to enable the rod anchor block 134 to be moved to and held in its clamped or latched position (shown in Figure 5 ).
  • the technician will move the lever 136 toward the release position (toward the rod anchor block 134 in the direction of arrow 164), thereby disengaging the lever 136 from the rod anchor block 134.
  • the principal mating portions of the latch surfaces 154,156 be substantially tangential to, or an arc of, a circle 155 that is concentric with the lever pivot axis 153.
  • Releasable mount 210 a version of a mount, is illustrated in Figure 6 .
  • Releasable mount 210 is similar to mount 10 described above, and features with similar functions are indicated by similar reference numbers.
  • the mount 210 includes a base having a pair of journal boxes or members (not visible in Figure 6 , but similar to the journal boxes or members 32 of Figures 2, 3 , and 4 ) integrally mounted to a ring 216 on opposite sides of a rod anchor block 234.
  • the rod anchor block 234 is pivotally mounted to the journal boxes or members of the base by pivot pin 238 so that it can be pivoted as indicated by arrow 239 about the pivot axis defined by the pivot pin 238.
  • mount 210 includes a release pin 272, which releasably engages a hole 276 in the ring 216 or in any other base component (not shown) that can be mounted on, or affixed to, ring 216.
  • Pin 272 is mounted for reciprocal motion in a cylindrical hole 278 in the rod anchor block 234.
  • a spring 274 biases the pin 272 toward its clamped or latched position (shown in Figure 6 ) at which an end of the pin extends from the rod anchor block 234 and into engagement with the hole 276 when the rod anchor block 234 is in the operative position.
  • the technician will move the knob 280 toward the release position (in the direction of arrow 284), thereby disengaging the pin 272 from the ring 216, and allowing the anchor block 234 to pivot about pivot pin 238, as shown by arrow 239.
